“Most software that’s used for monitoring comes from software companies. We built this software out of operational need and we built it as users of the technology,” said Optanix CSO Edmond Baydian.
The list of technologies that has been created because of the limitations of traditional, enterprise-grade relational databases is quite long, and yet these tried and true technologies persist at the heart of the modern enterprise. …

Things aren’t all bad news for Huawei. T-Mobile Poland confirmed that Huawei is the sole vendor supporting its 5G network.
The NSX Service Mesh beta will initially support Cloud PKS (formerly known as VMware Kubernetes Engine or VKE), but VMware plans to extend it to any Kubernetes environment.
Cumulus already offers its NOS on lots of different hardware. But this is Lenovo’s first foray into the disaggregated switch model.
The latest numbers from IHS Markit show that SD-WAN revenue grew 23 percent from the previous quarter to $284 million. VMware continues to hold the No. 1 spot.
Recently, I posted a video short take I did on BGP optimal route reflection. A reader wrote in the comments to that post:
…why can’t Router set next hop self to updates to router E and avoid this suboptimal path?
To answer this question, it is best to return to the scene of the suboptimality—
To describe the problem again: A and C are sending the same route to B, which is a route reflector. B selects the best path from its perspective, which is through B, and sends this route to each of its clients. In this case, E will learn the path with a next hop of A, even though the path through C is closer from E’s perspective. In the video, I discuss several ways to solve this problem; one option I do not talk about is allowing B to set the next hop to itself. Would this work?
Before answering the question, however, it is important to make one observation: I have drawn this network with B as a router in the forwarding path. In many networks, the route reflector is a virtual machine, or a *nix host, and is not capable of forwarding the traffic Continue reading

Australia vs. encryption: The Australian Parliament has passed a law that requires tech companies to give law enforcement agencies there access to encrypted communications, the New York Times reports. Several tech companies and privacy groups opposed the law, saying it hurts efforts to protect data from hackers. Fortune, which called the law “draconian,” says it will create headaches for large tech companies.
Slow rolling: While several news stories this year talked about quantum computing being an eventual threat to encryption, that possibility is still more than a decade away, according to a report from the U.S. National Academies of Sciences, Engineering, and Medicine. The U.S. may need to invest heavily in quantum computing to retain a global lead in the technology, the report recommends. Nextgov has the story.
Filling the pipes: Botnets of compromised Internet of Things devices make up more than three quarters of the malware on communication service provider networks this year, up from 33 percent of the malware in 2016, Infosecurity reports. Hackers are increasingly targeting IoT devices instead of PCs and other traditional systems.

We are excited to introduce VMware NSX® Service Mesh. Built on the foundation of Istio, this VMware offering will extend the capabilities of the Istio service mesh technology to bring visibility, control, and security at the application layer to microservices, the data they access, the users that interact with them, as well as traditional monolithic applications. In short, NSX Service Mesh will enable visibility, control, and security for services, data, and users at the API level. This acts as a natural evolution of cloud-native constructs and will act as an extension of the NSX-T Data Center platform’s replication of networking and security services in software, which is applied directly to containers via the Container Network Interface (CNI).
With the rise of cloud-native architectures built on distributed microservices, developers are encountering challenges with visibility, management, and control of these new applications. The microservices that these apps are comprised of are developed on cloud-native platforms like Kubernetes or Cloud Foundry, using a variety of programming languages, and often across multiple cloud environments. In addition, these applications consist of many more endpoints to scale, secure, and monitor than in traditional ones. This ultimately Continue reading
